After failing to help rescue a boy from being kidnapped, Sakuya Morita (name is changeable) has since believed it would have been better for her to have been born a boy.

One day, she's given the chance to try the new attraction at the Dream World virtual theme park, called East Tower. Dream World is a virtual world where your inner wish can come true. Inside, Sakuya manages to transform into a man like she has wished for. Later she finds other participants have also changed their appearances. And then an incident occurs, trapping everyone inside the virtual world.

What actually happened? Will they be able to return back to reality? Everything is not as simple as it seems.[1]
